Study On The Spatial Structure Of Xunhua County

Xunhua County,located in the upper reaches of the Yellow River,is the only Salar Autonomous County in China and a city with distinct ecological and cultural characteristics.In recent years,with the rapid expansion of urban space and the continuous increase of urban scale,a series of problems gradually appear in the process of urban construction,such as the destruction of ecological environment,the disorder of urban function layout,and the loose road organization.Under the premise of protecting the fragile ecological environment in the upper reaches of the Yellow River,it is particularly important to reasonably layout the functions of urban clusters,deal with the traffic organization problems of the belt-shaped cities,realize the efficient spatial organization of population and socio-economic activities,and promote the healthy development of the spatial structure of Xunhua County.This study is divided into three parts,the first part is the basis of the study,including the first and second chapters.The first chapter discusses the research background,research object and related concepts,domestic and foreign research situation.The second chapter interprets the current characteristics of the spatial structure of Xunhua County,including the general situation of the county,the construction process and current situation of the county,and forms the basic understanding of Xunhua County.The second part is the main body of the study,including the contents of the third,fourth and fifth chapters.It focuses the research on the spatial structure of Xunhua County on the three parts of ecological pattern,functional layout and road system,which constitute the three parallel chapters of this paper.It makes a systematic in-depth analysis and provides suggestions for the future development of Xunhua County spatial structure through qualitative and quantitative analysis.In terms of ecological pattern,analyze the ecological security pattern of the county,delimit the external ecological bottom line of the county,and reasonably select the direction of urban development.Next,build the ecological corridor inside the county,add green patches,and form the ecological pattern of the county together with the surrounding ecological background.In the aspect of function layout,it discusses the function orientation of the county under the influence of regional strategy,natural resources and national culture,reasonable layout of function divisions,and Realization of intensive use of land and coordinated development among groups;in the aspect of road system,it focuses on how to effectively realize the traffic connection between groups and ease the traffic between internal and external groups under the restriction of valley topography Dun,improve the urban internal traffic efficiency.Through the above three parts of Xunhua County spatial structure development to provide guidance and suggestions.The third part is the research summary,which is the summary and sublimation of the main part of the research.By integrating the optimization path of the county's spatial structure,the paper puts forward the future vision of the development of Xunhua County's spatial structure,obtains the comprehensive optimization plan,and proves the rationality and scientificity of the above optimization results through the simulation test,in order to provide guidance for the spatial construction of Xunhua County,as well as provide guidance for it He similar types of river valley city space development to provide reference,rich related research results.
